ios - ActionSheetStringPicker Picker View 的 UITextView 问题

Question

首先在这里查看 3 个屏幕截图。

屏幕截图 1:主题是 UITextview 字段。当我点击主题文本字段时，会出现普通键盘。现在这里没有问题。

屏幕截图 2:优先级是 UITextfield View 。这里我使用 UIActionsheet Picker View 。当我单击优先级文本字段选择器时，将出现如屏幕截图所示。这也工作正常。

我的问题 :当我通过滚动直接从主题 TextView 单击优先级文本字段时，不使用键盘上的完成按钮或下一步按钮。然后下一个问题来了。

或者当我将 UITextview 移动到其他任何其他文本字段时，例如帮助主题文本字段或源文本字段(在此文本字段中使用 UIActionsheet。)同样的问题出现了。

请参见屏幕截图 3。

在这里，keyboard 和 UIActionsheet 都出现了。这里键盘没有隐藏，它仍然出现。它不会出现在这里，当我将 UITextView 移动到下一个文本字段时，即在 UIActionsheet 选择器中，它只显示 Picker VIew。

我没有得到什么问题。任何人请告诉我解决方案。

这是一些代码，

@interface EditDetailTableViewController ()
{
    NSNumber *help_topic_id;
    NSNumber *priority_id;



    NSMutableArray * pri_idArray;
    NSMutableArray * helpTopic_idArray;
}

- (void)helpTopicWasSelected:(NSNumber *)selectedIndex element:(id)element;
- (void)priorityWasSelected:(NSNumber *)selectedIndex element:(id)element

- (void)actionPickerCancelled:(id)sender;
@end

@implementation EditDetailTableViewController

- (void)viewDidLoad {
    [super viewDidLoad];


    help_topic_id=[[NSNumber alloc]init];
    priority_id=[[NSNumber alloc]init];
}

-(void)removeKeyBoard
{
    [self.subjectTextView resignFirstResponder];
}

- (IBAction)priorityClicked:(id)sender {
    [_priorityTextField resignFirstResponder];

    if (!_priorityArray||![_priorityArray count]) {
        _priorityTextField.text=NSLocalizedString(@"Not Available",nil);
        priority_id=0;

    }else{
        [ActionSheetStringPicker showPickerWithTitle:@"Select Priority" rows:_priorityArray initialSelection:0 target:self successAction:@selector(priorityWasSelected:element:) cancelAction:@selector(actionPickerCancelled:) origin:sender];
    }

}

- (IBAction)helpTopicClicked:(id)sender {
    [_helpTopicTextField resignFirstResponder];

    if (!_helptopicsArray||!_helptopicsArray.count) {
        _helpTopicTextField.text=NSLocalizedString(@"Not Available",nil);
        help_topic_id=0;
    }else{
        [ActionSheetStringPicker showPickerWithTitle:@"Select Helptopic" rows:_helptopicsArray initialSelection:0 target:self successAction:@selector(helpTopicWasSelected:element:) cancelAction:@selector(actionPickerCancelled:) origin:sender];
    }

}

- (void)priorityWasSelected:(NSNumber *)selectedIndex element:(id)element {
    priority_id=(pri_idArray)[(NSUInteger) [selectedIndex intValue]];

    //self.selectedIndex = [selectedIndex intValue];

    //may have originated from textField or barButtonItem, use an IBOutlet instead of element
    self.priorityTextField.text = (_priorityArray)[(NSUInteger) [selectedIndex intValue]];
}

- (void)helpTopicWasSelected:(NSNumber *)selectedIndex element:(id)element {
    help_topic_id=(helpTopic_idArray)[(NSUInteger) [selectedIndex intValue]];
    // self.selectedIndex = [selectedIndex intValue];

    //may have originated from textField or barButtonItem, use an IBOutlet instead of element
    self.helpTopicTextField.text = (_helptopicsArray)[(NSUInteger) [selectedIndex intValue]];

Answer 1

我认为以下IBAction代码:

- (IBAction)staffClicked:(id)sender {
    [self.view endEditing:YES];
    if (!_staffArray||!_staffArray.count) {
        _assignTextField.text=NSLocalizedString(@"Not Available",nil);
        staff_id=0;
    }else{

        [ActionSheetStringPicker showPickerWithTitle:NSLocalizedString(@"Select Assignee",nil) rows:_staffArray initialSelection:0 target:self successAction:@selector(staffWasSelected:element:) cancelAction:@selector(actionPickerCancelled:) origin:sender];
    }
}

...以及以下方法:

- (void)staffWasSelected:(NSNumber *)selectedIndex element:(id)element
{
    staff_id=(staff_idArray)[(NSUInteger) [selectedIndex intValue]];
    self.assignTextField.text = (_staffArray)[(NSUInteger) [selectedIndex intValue]];
}


- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField {
    return NO;
}

...将为您解决您的问题。
